Compounds of the formula I ##STR1## wherein R.sub.2 is hydrogen or an organic acid residue; R.sub.3 is methyl or ethyl; R.sub.4 is hydrogen or methyl; ##STR2## wherein R.sub.1 is lower alkyl; and ##STR3## and when R.sub.2 is a dibasic acid residue, the physiologically acceptable salts thereof with the free acid moiety of the R.sub.2 group, are physiologically active, e.g., are diuretics having aldosterone antagonist effects.
公式I的化合物为##STR1##其中R.sub.2为氢或有机酸残基;R.sub.3为甲基或乙基;R.sub.4为氢或甲基;##STR2##其中R.sub.1为较低的烷基;以及##STR3##当R.sub.2为二元酸残基时,其与R.sub.2组的游离酸部分的生理上可接受的盐是生理活性的,例如,具有醛固酮拮抗剂效应的利尿剂。
